How to fix a whining noise in Car stereo system

How to fix a high pitched whining noise in a car stereo. I have had issues with sound quality in my car stereo and I went out to find the answer to resolve my problems.



The car stereo sounded great but there was a high pitched whining noise when the car was "on". It was loud and interfered with the sound quality of the sertero. This is caused by interference of audio signals by the electrical waves by the cars power systems. There are multiple types of noise that can be causing an issue. I drilled down my issue to "ground loop noise".


The Fix

A ground loop isolator takes out much of the noise associated with engine whine and power cord crossing. I used the ground loop isolator to eliminate the problem noise from my system. It was an easy install that is highly recommended.


  1. Locate RCA cables to the AMP
  2. Note the position of the referenced RCA cables
  3. Unplug the RCA's from the AMP and re-plug them in to the Ground Loop Isolator.
  4. Plug the new RCA cables into the respective place on the AMP were you originally took them out of.
